在日常的学习和工作中，经常要安装一些软件，但是如果仅是配置本地yum源的话，非常的局限，并且也无法做到在线升级或在线安装软件；
所以为了方便日常的学习和工作，我们来配置一下国内的yum源以及epel源（如果为了方便，大家使用云服务器就好了，这些都是配置好的！）
1、首先进入/etc/yum.repos.d/目录下，新建一个repo目录，用于保存系统中原来的repo文件
[root@wjq1 ~]# cd /etc/yum.repos.d/ [root@wjq1 yum.repos.d]# ll drwxr-xr-x. 2 root root 187 Jun 12 2018 repo
2.在CentOS中配置使用网易和阿里的开源镜像
2、到阿里开源镜像站点下载系统对应版本的repo文件
[root@wjq1 yum.repos.d]# wget http://mirrors.aliyun.com/repo/Centos-7.repo --2019-02-15 12:12:53-- http://mirrors.aliyun.com/repo/Centos-7.repo Resolving proxy.tencent.com (proxy.tencent.com)... 10.1.156.88 Connecting to proxy.tencent.com (proxy.tencent.com)|10.1.156.88|:8080... connected. Proxy request sent, awaiting response... 200 OK Length: 2523 (2.5K) [application/octet-stream] Saving to: ‘Centos-7.repo’ 100%[==========================================================================================================>] 2,523 --.-K/s in 0s 2019-02-15 12:12:53 (67.6 MB/s) - ‘Centos-7.repo’ saved [2523/2523] [root@wjq1 yum.repos.d]# ll total 4 -rw-r--r-- 1 root root 2523 Jun 16 2018 Centos-7.repo drwxr-xr-x. 2 root root 217 Feb 15 12:14 repo
或者手动下载repo文件并上传到/etc/yum.repos.d/目录
阿里云开源镜像：阿里云开源镜像
3、清除系统yum缓存并生成新的yum缓存
[root@wjq1 yum.repos.d]# yum clean all #清除系统所有的yum缓存 Loaded plugins: fastestmirror, langpacks Cleaning repos: base extras updates Cleaning up everything Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos Cleaning up list of fastest mirrors [root@wjq1 yum.repos.d]# yum makecache # 生成yum缓存 Loaded plugins: fastestmirror, langpacks Determining fastest mirrors * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com base | 3.6 kB 00:00:00 extras | 3.4 kB 00:00:00 updates | 3.4 kB 00:00:00 (1/12): base/7/x86_64/group_gz | 166 kB 00:00:00 base/7/x86_64/primary_db FAILED http://mirrors.cloud.aliyuncs.com/centos/7/os/x86_64/repodata/6614b3605d961a4aaec45d74ac4e5e713e517debb3ee454a1c91097955780697-primary.sqlite.bz2: [Errno 14] HTTP Error 504 - Gateway Timeout Trying other mirror.

4、安装epel源
[root@wjq1 yum.repos.d]# yum list | grep epel-release epel-release.noarch 7-11 extras [root@wjq1 yum.repos.d]# yum install -y epel-release Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com Resolving Dependencies --> Running transaction check ---> Package epel-release.noarch 0:7-11 will be installed --> Finished Dependency Resolution Dependencies Resolved ==================================================================================================================================================== Package Arch Version Repository Size ==================================================================================================================================================== Installing: epel-release noarch 7-11 extras 15 k Transaction Summary ==================================================================================================================================================== Install 1 Package Total download size: 15 k Installed size: 24 k Downloading packages: warning: /var/cache/yum/x86_64/7/extras/packages/epel-release-7-11.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY Public key for epel-release-7-11.noarch.rpm is not installed epel-release-7-11.noarch.rpm | 15 kB 00:00:00 Retrieving key from http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7 Importing GPG key 0xF4A80EB5: Userid : "CentOS-7 Key (CentOS 7 Official Signing Key) <security@centos.org>" Fingerprint: 6341 ab27 53d7 8a78 a7c2 7bb1 24c6 a8a7 f4a8 0eb5 From : http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : epel-release-7-11.noarch 1/1 Verifying : epel-release-7-11.noarch 1/1 Installed: epel-release.noarch 0:7-11 Complete! # epel源安装成功，比原来多了一个epel.repo和epel-testing.repo文件 [root@wjq1 yum.repos.d]# ll -rw-r--r-- 1 root root 2523 Jun 16 2018 Centos-7.repo -rw-r--r-- 1 root root 951 Oct 3 2017 epel.repo -rw-r--r-- 1 root root 1050 Oct 3 2017 epel-testing.repo drwxr-xr-x. 2 root root 217 Feb 15 12:14 repo
5、使用阿里开源镜像提供的epel源
[root@wjq1 yum.repos.d]# wget -O /etc/yum.repos.d/epel-7.repo http://mirrors.aliyun.com/repo/epel-7.repo --2019-02-15 12:24:15-- http://mirrors.aliyun.com/repo/epel-7.repo Resolving proxy.tencent.com (proxy.tencent.com)... 10.1.156.88 Connecting to proxy.tencent.com (proxy.tencent.com)|10.1.156.88|:8080... connected.

6、再次清除系统yum缓存，并重新生成新的yum缓存
[root@wjq1 yum.repos.d]# yum clean all Loaded plugins: fastestmirror, langpacks Repository epel is listed more than once in the configuration Repository epel-debuginfo is listed more than once in the configuration Repository epel-source is listed more than once in the configuration Cleaning repos: base epel extras updates Cleaning up everything Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos Cleaning up list of fastest mirrors [root@wjq1 yum.repos.d]# yum makecache Loaded plugins: fastestmirror, langpacks Repository epel is listed more than once in the configuration Repository epel-debuginfo is listed more than once in the configuration Repository epel-source is listed more than once in the configuration Determining fastest mirrors * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com base | 3.6 kB 00:00:00 epel | 4.7 kB 00:00:00 extras | 3.4 kB 00:00:00 updates | 3.4 kB 00:00:00 (1/18): base/7/x86_64/group_gz | 166 kB 00:00:00 (2/18): base/7/x86_64/filelists_db | 7.1 MB 00:00:01 (3/18): epel/x86_64/group_gz | 88 kB 00:00:00 (4/18): base/7/x86_64/other_db | 2.6 MB 00:00:00 (5/18): epel/x86_64/updateinfo | 959 kB 00:00:00 (6/18): epel/x86_64/prestodelta | 4.6 kB 00:00:00 (7/18): base/7/x86_64/primary_db | 6.0 MB 00:00:01 (8/18): epel/x86_64/primary_db | 6.6 MB 00:00:01 (9/18): epel/x86_64/filelists_db | 11 MB 00:00:02 (10/18): extras/7/x86_64/prestodelta | 47 kB 00:00:00 (11/18): extras/7/x86_64/filelists_db | 230 kB 00:00:00 (12/18): extras/7/x86_64/primary_db | 179 kB 00:00:00 (13/18): extras/7/x86_64/other_db | 117 kB 00:00:00 (14/18): updates/7/x86_64/prestodelta | 333 kB 00:00:00 (15/18): epel/x86_64/other_db | 3.2 MB 00:00:00 (16/18): updates/7/x86_64/filelists_db | 1.9 MB 00:00:00 (17/18): updates/7/x86_64/other_db | 331 kB 00:00:00 (18/18): updates/7/x86_64/primary_db | 2.4 MB 00:00:00 Metadata Cache Created
7、查看系统可用的yum源和所有的yum源
